A quick way to find answers to many questions in SL is to look in the Knowledge Base.  In this case, see https://community.secondlife.com/t5/English-Knowledge-Base/Using-voice-chat/ta-p/700169#Section_.8.2 .

There may be a better answer, if you want to do more than just try it out.  The voice morphing pack is a commercial product, offered through license to Linden Lab.  You can also buy it directly from the providing company, where I am told that you can get more flexible options. Buying their product directly might cost you less in the long run than paying a monthly rental fee.
